I am just getting hammered with failing AC systems this year, we just got the 9th repair request in basically the last 2 months. And I am learning that once again we are changing AC refrigerants, which means no backwards compatibility, higher cost and apparently also new tools for installers?

Here is the gist, wondering what you guys are doing to deal with this. In hindsight, I should have stocked up on ACs.

In 2025, new air conditioning systems will no longer use the older R-410A refrigerant due to environmental regulations. Instead, they will utilize refrigerants with lower global warming potential, primarily R-454B and R-32. These new refrigerants are classified as A2L refrigerants, which are mildly flammable but still considered safer than older refrigerants like R-22.

Phasing out R-410A: The EPA is phasing out R-410A due to its high global warming potential (GWP).

New refrigerants: R-454B and R-32: These are the primary replacements for R-410A in new systems.

A2L Classification: These new refrigerants fall under the A2L classification, meaning they are mildly flammable.

Safety Measures: New HVAC systems using A2L refrigerants will incorporate safety features like leak detectors and automatic shut-off valves.

No Retrofitting: Existing systems cannot be retrofitted to use the new refrigerants.

Cost Implications: New systems using A2L refrigerants will likely be more expensive due to the new technology and safety features.

I am not against reducing greenhouse emissions, but it seems like we are really barking up the wrong tree with AC refrigerants - meanwhile, we are burning more coal than ever, I believe 8 billion tons per year, and we are trying to save the planet one AC system at a time...
